Abstract

Two widely used statistical approaches to reconstructing past climate histories from climate "proxy" data such as tree rings, corals, and ice cores are investigated using synthetic "pseudoproxy" data derived from a simulation of forced climate changes over the past 1200 yr. These experiments suggest that both statistical approaches should yield reliable reconstructions of the true climate history within estimated uncertainties, given estimates of the signal and noise attributes of actual proxy data networks. © 2005 American Meteorological Society.
